TIMI myocardial perfusion grade 3

Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]

Overview

Normal entry and exit of dye from the microvasculature. There is the ground glass appearance (“blush”) or opacification of the myocardium in the distribution of the artery that clears normally and is either gone or only mildly persistent during the washout phase (i.e. dye is gone or is only mildly persistent after 3 cardiac cycles and noticeably diminishes during the washout).
